It is well established that health is inherently linked with well-being. The World Health Organization recognizes that health is “a state of complete physical, mental and social well-being and not merely the absence of disease..." (WHO, 1948). In schizophrenia spectrum disorders, well-being is a key element in both the process of recovery and relapse (Schennach-Wolff et al., 2010). Previous reviews regarding the effectiveness psychological interventions for psychosis have focused on positive symptoms and general psychopathology (Wykes, et al., 2008; Jauhar et al., 2014). The current meta-analytic study focuses on the effectiveness of psychotherapeutic interventions on well-being for people with schizophrenia and related disorders.

The inclusion criteria for the systematic review is: 1) RCTs of a psychological intervention; 2) Randomization of the study subjects and the presence of a control condition; 3) Interventions for individuals with diagnoses of schizophrenia spectrum disorders (DSM-IV); and 4) At least one outcome measure of well-being or quality of life.

In general, psychotherapy for schizophrenia has a therapeutic effect on well-being in the small range. The moderating effects of the specific characteristics of the interventions, settings and subjects will be examined. Strategies to enhance well-being will be briefly discussed.
